Owain Tudur Jones has followed Swansea team-mates Alan Tate and Shaun MacDonald in agreeing a new contract with the Championship new boys.
The once-capped Wales midfielder, 23, has suffered with serious knee and ankle injuries since joining from Welsh Premier side Bangor in July 2005.
Despite playing eight games this season he has been given a year extension.
"I'm delighted to get that further 12 months at a special time for the club. It's a big boost for me," Jones said.
"I'm really looking forward to pre-season training where it's a chance for me to get fit and to try and get myself to the level of the rest of the boys.
"It's an exciting time for the club and to be part of that is a big thing.

"All I can do is get myself as fit as possible, try and impress the manager [Roberto Martinez] on a daily basis and if I do that then I'm giving myself a chance to progress my career and stay with this club as long as possible."
Jones needed the intervention of renowned American knee specialist Dr Richard Steadman to cure a career-threatening injury that wrecked his 2006/7 season.
After recovering from that set-back, Jones then fractured his ankle last autumn but again fought back to fitness.
His reward was a long-delayed first Wales cap, coming on as a substitute in the 2-0 friendly win away to Luxembourg last March.
Jones was then able to play his part in the latter end of the season, as Swansea marched to the League One title and promotion to the Championship.
"It's been tough. It hasn't been an easy couple of years but I've learnt to deal with it," Jones added.
"To get over something like this stands you in good stead, you know that you can deal with anything that happens to you in your football career.
"It's a case now of not dwelling on the injuries, it's about moving on and looking forward to the challenges ahead."
Swansea club captain Garry Monk, Kristian O'Leary, Kevin Austin and Dennis Lawrence have all been offered new one-year contracts after making enough appearances last season to trigger new deals.
